基于移动窗口法,对2014年苗二河流域森林景观格局进行分析。结果表明:非林地和有林地为优势地类景观,面积大,斑块形状较复杂,分布广泛;无立木林地为劣势地类景观,面积小,斑块形状较规则,分布比较集中;森林景观适宜景观粒度为150 m;森林景观适宜窗口尺度为900 m。基于粒度效应、面积信息损失精度和移动窗口法对苗二河流域森林景观格局的研究,可为优化流域森林景观提供参考。
Based on the moving window method, the forest landscape pattern in Miao River Basin in 2014 was analyzed. The results showed that non-woodland and woodland were dominant landscapes, with large area and complex patch shape. There was a wide range of patch shape in the non-woodland and woodland. The suitable landscape size is 150 m and the suitable window size for forest landscape is 900 m. The research on the forest landscape pattern in Miao Erhe River Basin based on the grain size effect, the precision of area information loss and the moving window method can provide references for the optimization of the forest landscape.
